A very soft grade of finishing mop. Slightly softer than the G quality mop and slightly harder than the WDR quality loose fold mops. Ideal if you find the G quality mop a little too hard. The mops have leather centre washers, no staples and have been finished so they can be used straight away. On metals compounds such as 480W, 480BLF, P175 and M5 are commonly used. Very popular in the Jewellery and fine finishing trades. On resins and plastics then use this mop with fine compound such as P175,M5 and G52.
